. PE TH-annoy; NEW mas-nnacoaroanlrron EFNEW'JERSEYn I a Be it known that LSUMN-ER of New York; have invented a certain'new and. useful Improvement in Safes, of which the following is aspecification. a

This invention concerns safes, vaultsand. the like, and has referenceparticularly to.

the construction of theldoors therefor.

I Theobject of the invention is to provide a door fora safe ofan improved constructlon, the improvementsfbeing directed to makingthe locking mechanism for the door more, reliable and effective and guarding the. employment of an explosive.

The invention involves the provision of a door for a safe constructed 'to provide one or more chambers within the'door and referably nearer the outer- .face' than the inner. face, 1n which-gases presentin an explosion vmay expand, these chambers beingclosedat the edge of the doorby' thin metal which may be readily ruptured, and this metallic closure for the chambers being setin a slightdistance. from the edge of the door so as to" form a trap in which an explosive inliquid form will be caught,

"The. preferredembodiment of raj invendrawings, in which- Figurel v s: a central section through the door and a portion ofthe-safe; Fig. 2 is a rear face view of'the. door'and a portion of the safe,.the. latter bein broken awa and sectioned in part; and Flg. 3 is a detai View v illustrating a slight modification.

Referring to these; drawings, 1 indicates the wall ofthesafe or vault, in' which is a circular opening to receive the door 2 This circular door ma be supportedin-the usual" manner, permitting it to be, 'swung around on pivots into its openin 1n the wall of the safe and then turned on Its axis to lock it in ingfor the door in the safe 1, the projec tions 3 passing through the spaces between adjacent projectlons 4 when the door 1s moved to. the closed position. The door 2 is Specification o1" Lettezikbtbnh: Application manner-2mm. sea-infr 423,808.

Chambers 5 'aregclosed at the edge of the door by emu; ofthin metal which maybe readil rap:

' tured. .In the manufacture of the the chambers 5 are soformedYasLto be pam-e5" at theedge of. the door" and afterwards ag'f. strip ofsheet-metal -7 isseeured in position; as shown in Fig. 1, so as to close the chm: 1-. bers 5, this strip extendingentirely around! strip- 7 in. position,;

the strip is "set back. om the edge" of. they door a slight distance, .as shown' in 1,, so as to provide a narrow space 8, in which a liquid explosive insertedbetweenthedoon strip 7 is so thintthatonthe explosionof' this liquid the strip would be instantl';

gases to ,expan within the chambers'5.

In Fig. 3, Ihave shown a slight. 8'0 tion of. the construction illustratedin Fig; 4 1, this consisting inthe provisionof a strip 9"whijch. corresponds to the 7", and. which is considerably thinner-mt one. than at the. other. This strip is mountedin 85.- position within. the chambers 5 with outer face of theuthicker portion flush. with f the edge of the door, A small chamberv 10 is thus L provided extending around. the; edge; a

of. the door adjacent to the thinner.

of strip 9, which will serveto trap ahquidexplosive; M

When .the" door is inserted. in its-opening;

1n this osition by either. or-hoth of two indepen ent locks, a combination lock alnd. an automatic time lock, each of these-locks having. its individualv bolt-work. "'One"ofi these. locks, preferably the conibination-lock, is. located within the chamber-5, between. the outer and inner sections of the door. This lock-is shown'in Fig, 1 and consists of one or more bolts 11 operated by a lever 12, this lever being operated in turn:. by aplurality ofnotched d'isks'13. Thesedisks are.

4 1 strip 9, and when this explosive is detonated rotated in the usual manner'by a gear 14: m with agear 15 on a spindle 16 which extends'through the outer section of Fig. 1, the strip 7 is provided with openings the door 2 and-is provided with an operating handle 17 on its outer end. The base of the operating handle 17 is provided with scale markings in the usual manner, cooperating with similar markings on anannulus'adjacent to which the base of the handle turns to indicate the required extent of turning movement of the handle 17 in' order to operate the combination-lock. As shown in through which the ends of bolts 11 may pass, the ends of-thesebolts being adapted to enter openings 18. provided in the wall of the opening in the safe for door 2.

Theautomatic time-lock 19 is secured to erate the lock to release' the bolts 20 at the desired time and permit them to be withdrawn from the openings 21 by a suitable spring provided for this purpose.

As will readily be seen, with a door constructed as above described,'a liquid explosive inserted in the crack between the wall 'l and door 2 will become trapped in the narrow space between the door-jamb and the strip 7 or the narrow portion of the the striphlor 9 will be instantly ruptured and'the gases""will expand within the cham- "If the explosion is sufliciently se- "vere, the front section of the door, that is, the portion lying in front of the chambers 5, Wlll be blown out, but the section of the door in rear of the chambers 5 will remain in. place and prevent access to the interior of the safe. Also, by providing two locks which are entirelyindependent,

' each having itsindividual bolt-work, a much moresecure and reliable locking of the door is effected.

.With the arrangement of these locks here shown, that is, one mounted within the chamber 5 and the othe'r secured to the rear face of the door, the partsof the two locks are not so cramped as to render their operation any the less reliable, and yet space at the edge of the door, back from the edge of the door to within the safe available for the storage of valuables is not taken u by these locks.

Having now describe m inventionQwhat I claim "as new therein an desire to secure by Letters Patent is as follows 1. In a safe, a door formed of rigidly connected front and rear sections and having a chamber between said sections, said chamber extending outwardly toward the edge of the door and bein closed at said ed e by a readily destructibIe wall, substantia ly; as set forth.

2. In a safe, a door formed of rigidly connected front and rear sections and having a chamber between said sections, said chamber extending outwardly toward the .edge of the door and beingclosed at said edge by a readily destructib e wall being positionedto providea narrow chamber between it and the door-jamb when the dooris closed, substantially as set forth.

3.111 a safe, a door having a chamber formed therein between its .front and rear faces, and a thin metallic stri secured to the door in osition to c'losesai chamberat the edge o the door, substantially as set forth. I 4. In a safe, a door having a chamber formed therein between its front and rear faces, and a thin metallic stripsecured to the door in position to close said chamber said strip being set provide a narrow chamber between it and the doorjamb when the door is closed, substantially as set forth.

5. In a safe, a circular door formed of rigidly connected front and rear sections and havin a chamber between said sections extending outwardly to the edge of the door, anda strip of sheet-metal extending around the door and closing said chamber at the edge of the door,.substantially as set forth.

6. In-a safe, a circular door formed of rigidly connected front and rear sect ons and having a chamber between said sections exwall and said tending outwardly to the edge of the door, a
